Abstract

Pipa bawah tanah menjadi elemen yang sangat penting dalam dunia industri salah satunya untuk mengalirkan fluida. Masalah serius yang sering dihadapi adalah kontak antara pipa dengan tanah dan lingkungan yang dapat menimbulkan korosi. Maka dari itu, dibutuhkan penanganan khusus agar tidak terjadi kerusakan dan ketidakstabilan tanah. Salah satu upaya awal untuk menangani hal tersebut adalah dengan melakukan pemetaan zona korosi bawah permukaan yang pada penelitian Tugas Akhir kali ini dilakukan dengan metode Time Domain Induced Polarization dengan konfigurasi dipole-dipole sebanyak 5 lintasan. Respon chargeability terhadap korosivitas tanah pada lokasi penelitian secara rata-rata menunjukkan hubungan yang berbanding lurus, semakin tinggi nilai chargeability maka semakin tinggi tingkat korosivitas tanah. Zona korosivitas tanah sangat ringan hingga sedang menyebar pada kedalaman 0-4.72 meter sedangkan zona korosivitas tanah tinggi hingga sangat tinggi berada pada kedalaman 2.72-4.72 meter. ============================================================================== The underground pipe becomes a very important element in the industrial world, one of the usefulness is to flow fluid. The contact between the pipe with the soil and the corrosive environment might be a concern. A certain deal is needed to avoid damage and soil instability. One of the initial efforts to handle this problem is by conducting a mapping of the soil corrosivity zone that was conducted by Time Domain Induced Polarization method with dipole-dipole configuration of 5 trajectories. The chargeability response to the soil corrosivity at the study sites on average shows a proportional relationship, the higher the value of chargeability, the higher the level of soil corrosivity. Very mild to moderate soil corrosivity zone spreads at a distance of 0-4.72 meters while the soil corrosive zone is high up to very high at a depth of 2.72-4.72 meters.
